When Our Lady of Lourdes appeared to Bernadette Soubirous in 1858, she identified herself by saying, "I am the Immaculate Conception." This title was not understood by Bernadette, a young peasant girl, but correctly understood by the priest who had told her to ask the Lady who she was.

Mary, Mother of Jesus Christ, Eternal High Priest, Mother of all priests, and our Mother, help us respond generously to the Holy Spirit's request, through the voice of His Church, to offer up to God Eucharistic adoration for priests. Amen.
